They look amazing! How do they sound compare to your other infinitys?
The Monitor IIas are in beautiful condition.
I never heard them before and need to refoam the woofers but I'm sure they'll sound sweet.

Speed-drying out on the deck.
They should be up and running this evening.

Hello All,
In a short 6 months (since Nov last year), I have transformed from a person with no hobby - into an infinity and carver fan. I received much help from the AK community - with answers to my many questions (often so basic & naively embarrassing) about audio. I am still learning - but I enjoy every bit of my experience.
Speakers (from left to right): RS IIa, RS IIb, RS IIb, RS 2.5, Column 2, and Kappa 6.1 (photo - not arranged for listening).
Amplifiers: 2 tfm-45, 2 tfm-55, tfm-42, m-4.0t, m-1.5t, marantz 240
Preamp: B&K avp3090, carver c-1 (blown up), carver c-11 (blown up)
Source: Marantz dv7100, denon dcd 1560, Technics sl-1700 mk2 (coming soon)
As others have concluded, the IIb's are the best in that lot - but the watkins woofer sounds sweet and more wholesome to me. Wonder why they did not use it in the IIb's.
Most memorable experience was early February when I hooked up an m-1.5t (recently arrived from the post-office) to my system and it blew up (with a literal big bang that knocked off a fuse in my electrical box) - taking the c-1 to early demise with it. Sparks came off from that 1.5t but no burnt smell.
In the process, I have also learned how to dis-assemble and fix emim. I had two emims with ribbons starting to separate from the base. I built a jig (as suggested) and had no problem taking it off and putting it back. I used scotch tape to secure the ribbons back to the base. I also had an emim with resistance at ~8 ohm - caused by a slight damage to the strip near one terminal and damaged connectors. I applied the rear window defroster repair kit, soldered new wire in, and it solved the problem, bringing back the resistance to 3.4 ohm.
I am refoaming the woofers of the RS IIa - and I am planning to use this set to mod following what others did. I know nothing about electronics, so this will be a slow and long journey.
Weakest link is my preamp - I would like to go tube (AR SP-8 or SP-10) - or DIY tube preamp. Need to wait until I finally finish my house, hopefully by this fall. I know my limit - even with an understanding wife.
I never before realize that source can make a big difference. I thought all CDPs are the same, until I got the denon 1560, which blew the marantz dv7100 off the water. I am trying vinyl soon.
I actually felt guilty having that many infinity speakers but I got such a pleasure looking at and hearing these vintages. Such a refresher listening to them after a long day at the office.
Vintage setup with Infinity 6001.
My Infinity 8.1, RSb's, RSa's
Nice collection Satorusun! Apart from the bass response, how would you compare the tonal quality of the older RSb's to the 8.1's?
I lucked into a pair of these minty Monitor IIa'sand can't wait to get them up and running after a refoam.
It took awhile but it finally dawned on me the Peerless softdomes are larger than that of the 1 1/2ers" used in the Quantum lineup... the IIas using a 2" voice coil:scratch2:
Nice - definitely a rare find! I had a double-take when I saw the Peerless dome tweeter, thinking they must be Polks! I've seen photos of the Monitor IIA before but never realized they used that Peerless.
Interesting that the Peerless tweeter is run from 5 kHz - 10 kHz and the Walsh tweeter from there on up.
Infinty Qbs do sound nice especially with some strategic internal bracing
Reference Standard II's
